The Lowdown
Alright, folks, Rusty here. Let’s get into it. I’ve looked over the numbers for Kennebunk Beach, and I gotta be straight with you: this stretch of 16 days is about as flat and quiet as it gets around here. We’ve got a long dry spell ahead, so don’t be in any rush to wax up.
Right from the start on Friday the 21st of August, we’re looking at tiny 2ft surf from the ESE with a short 8-second period. The combined energy is only a weak 58. That’s not enough to get excited about. We get a clean, offshore ENE breeze in the morning but the swell is just too weak to bother with. That same limp pattern keeps going. Saturday the 22nd, Sunday the 23rd, Monday the 24th... it’s all the same story. The swell barely flickers. Tuesday the 25th, Wednesday the 26th, Thursday the 27th – it’s a whole week of nothing doing. The combined energy readings hover between a pathetic 22 and a barely moderate 159 on Monday afternoon, but even then, the wind is cross-onshore and messy. The water temp is sitting at 66°F which is about normal for the time of year, but you won’t be in the water long enough to notice.
We get a little flutter around Tuesday, September 1st. On that morning, we see the swell bump up to 5ft from the SSE with a combined energy of 167, which is moderate. The wind is light and cross-off from the east, keeping it clean. The wave comment finally says “surfable waves but very ordinary conditions.” It’s the best of a rough bunch, but let’s be real: the period is a short 6 seconds, so it’s going to be crumbly and weak. For an intermediate surfer, it’s something to paddle for, but it’s not a stand-out day by any stretch. That afternoon, the wind turns and it’s back to junk.
After that little tease, we fall right back into the abyss. Wednesday the 2nd of September gives us glassy conditions in the morning with a 1ft, 9-second SE swell, but again, the energy is only 65. That’s a flat day if I’ve ever seen one. Thursday the 3rd, Friday the 4th, Saturday the 5th... tiny, weak, and forgettable. The incoming energy is basically a whisper.
All in all, if you live for kitesurfing, a few of those afternoons with a slight cross-onshore breeze might look interesting, but for a paddle surfer, this is a long, hard stretch. Just one morning (September 1st) where it’s even borderline, and even then it’s only worth it for the keen intermediate who doesn’t mind small, short-period slop. The rest of the 16 days you can hang your board up.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
